1. SW4-G/20 Carbide Asphalt Milling Pick
The ALSKAR SW4-G/20 is a carbide-tipped road milling pick developed for asphalt pavement milling, surface removal, and road maintenance applications.
Designed for small cold milling machines, the SW4-G/20 combines a 20g tungsten carbide cutting tip with a steel pick body and a 20mm grooved round shank.
With an overall length of 88mm and a 48mm reference length, this compact milling pick is intended for operations using 0.35m and 0.5m milling equipment with compatible tool holder systems.
The SW4-G/20 is supplied exclusively in the grooved configuration and is available for professional contractors, equipment service providers, and industrial distributors.
2. 20g Tungsten Carbide Cutting Tip
The SW4-G/20 features a 20g tungsten carbide cutting tip designed for asphalt milling applications.
The carbide tip provides the cutting interface between the milling pick and asphalt pavement, while the supporting steel body transfers cutting forces through the tool holder system.
The tip geometry is intended for the cutting conditions associated with small road milling equipment.
Actual cutting performance and service life depend on pavement composition, abrasiveness, cutting depth, machine settings, and operating conditions.
3. Extractor Groove for Easier Tool Removal
The SW4-G/20 incorporates an extractor groove designed to assist with milling pick removal during maintenance and replacement.
The groove provides an access point for suitable extraction tools, helping operators remove worn cutting picks from compatible tool holders.
This configuration is especially relevant to road milling operations where cutting tools must be inspected and replaced regularly.
Available Configuration: With Groove Only.
4. 20mm Round Shank Construction
The SW4-G/20 features a 20mm round shank designed for installation in a matching road milling tool holder.
Its 88mm overall length and 48mm reference length provide defined dimensions for comparing the cutting pick with existing tool assemblies.
For proper installation, the pick geometry, shank dimensions, retaining system, and tool holder specifications must be checked before use.
The 20mm shank diameter alone does not guarantee compatibility with every 20mm milling tool holder.
